Paper Abstract

Introduction: Laparoscopic pyeloplasty is used for the repair of uretero-pelvic junction (UPJ) obstructions. Our aim was to do it using laser tissue soldering. Materials and Methods: We developed a tissue bonding system based on a CO2 laser, a temperature detector and infrared transmitting optical fibers, to obtain temperature controlled laser soldering of incisions. The system was then adapted for laparoscopic soldering of ureters of pigs. Results: We successfully carried out laparoscopic pyeloplasty in a porcine model, using a procedure based on CO2 laser soldering. Conclusions: Laparoscopic laser soldering was found to be faster than suturing, it was easier to use and provided watertight bonding. This technique will be useful in other surgical procedures.
